In chemistry, the haloform reaction is a chemical reaction in which a haloform (CHX3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base. The reaction can be used to … See more In the first step, the halogen dis-proportionates in the presence of hydroxide to give the halide and hypohalite. If a secondary alcohol is present, it is oxidized to a ketone by the hypohalite: If a methyl ketone … See more Laboratory scale This reaction forms the basis of the iodoform test which was commonly used in history as a See more Substrates are broadly limited to methyl ketones and secondary alcohols oxidizable to methyl ketones, such as isopropanol. The only primary … See more The haloform reaction is one of the oldest organic reactions known.

WebJun 21, 2016 · Haloform reaction with limited bromine. We were asked the reaction between 1 mole acetone and 1 mole B r X 2 in basic medium. Since only a limited amount of bromine was given I got the final answer as 1-bromopropan-2-one (mono bromo acetone). However, in the given solution the entire haloform reaction was shown with C H B r X 3 … WebApr 8, 2024 · Hint:We know that the reaction in which haloform (\[CH{X_3}\], where X is a halogen) is delivered by the thorough halogenation of a methyl ketone (\[RCOC{H_3}\], where R can be a hydrogen particle, an alkyl or an aryl), within the sight of a base is called haloform reaction.The reaction is utilized to change acetyl groups into carboxyl groups … WebApr 6, 2024 · An example of the haloform reaction is given below.
